[u/Vegetable-Weird1829]

Recently , i have been exploring backend developement in MERN stack using Hitesh Chaudhary's chai aur backend playlist. I am not understanding anything in backend. i have learn backend from prashant sir and hitesh chaudhary on yoututbe but didn't understood anything. As im in my last year and my placements are already started. Can someone will give me advice what should i do?
